The caller on WITF's "Smart Talk" radio show Friday asked the governor why gun shows are allowed at the Pennsylvania Farm Show Complex in Harrisburg and whether he'd support a ban.

Corbett said no one has ever suggested the idea to him before and promised to give it some thought.

But he said the Farm Show Complex is open to all businesses. He noted that prospective gun buyers at gun shows must be cleared through the Pennsylvania State Police instant background check system — just as they are when buying weapons from gun shops.
